Fossils dating back to 530 million years ago have been found in northwest China's Shaanxi Province, local public communication authorities said Thursday.
The colorful coral rocks were found on a hill in Hanyuan Town, Ningqiang County. Circular patterns can be seen in the rocks.
Prehistoric fossil researcher Wei Binghua identified the rocks as fossils of molluscan invertebrate pelagos, a low-level marine animal. --Xinhua
